I'm looking at 2 web sites

one has connection strings stored in

<appSettings>    
    <add key="SQLConn" value="Data Source=TEST\SQLEXPRESS;Initial Catalog=Validation;Connection Timeout=300;User ID=webuser;Password=password" />

the other has

   <connectionStrings>
    <add name="SQL" connectionString="Data Source=TEST\SQLEXPRESS;Initial Catalog=Validation;Connection Timeout=300;User ID=webuser;Password=password" providerName="System.Data.SqlClient"/>

Whats the best method ?

Thanks

Nick
